Biological revitalisation of highly devastated areas such as querries, depots and landfills is in Croatia, in terms of permanent green coverage, usually conducted with Austrian black pine (Pinus nigra Mill.). Until now research of other forest tree species utilization and their usage within sanation process haven’t been conducted. With this objective, in the fall of 2007, test field for scientific needs was established for research of biological sanation of querry Očura II with autochtonous tree and schrub species. Basic aim of this trial was to determine the possibility of application of autochtonous tree and shrub species in querry revitalisation. Trial was established in the border part of Očura II querry on already technically improved terracce. On this terracce layer of wasterock from querry was deposed which acts as foundation. Trial was established in two repetitions which depend on the soil type (deposed agricultural or forest humus substrate (soil)). In every repetition seedlings from nursery and from surrounding forest stands were planted. Seven pedological profiles have been dug up and additional observations have been conducted with pedological sonde. For indentification of pioneer forest species which come by nature on Očura querry locality, it was necessary to study and to determine vegetation, floristic composition of forest edges, as well as areas inside of querry on which natural vegetation begun to appear. Selection of plants for extraction was conducted in forest stands, on the top border area of querry, which was planned for clearcut in the near future with the aim of sequent exploitation of querry. Selected species were Flowering ash (Fraxinus ornus L.), Sycamore maple (Acer pseudoplatanus L.), Black poplar (Populus nigra L.), willows (Salix sp.), and European privet (Ligustrum vulgare L.). 546 plants od forest tree species was planted in total, which include 110 willows and poplar plants, 110 sycamore maple and 110 flowering ash plants and 216 bush species plants, which include 144 European privet and 72 Ruscus aculeatus plants. Selection of Ruscus aculeatus for this trial was based on preservation of individuall speciments of this endangered specie in the vicinity of it’s habitant which will be devastated by exploitation.
The results of test field monitoring indicate very good survival success of young plants. Outplanted plants on the test field were in very good health condition, except Ruscus aculeatus, which was planted with the aim of protection. For now conclusions about success of plants regarding the soil type could not be made, but there is a correlation between survival of plants and their breeding. At the time of survival observation nursery seedlings had higher average survival rate then plants extracted from surrounding stands. There is no difference in survival rate between plants planted on agricultural and forest soil in first year (91,2–91,1 %) but after secund year there are differences (81,8 % on forest soil, 87,7 % on agricultural soil) .
Survival of Sycamore maple is in range from 72,0 % to 93,3 %. Sycamore plants which have been extracted from forest stands have the lowest survival rate while plants planted on forest soil have lower survival (72 %) then plants planted on agricultural soil (73,7 %). Survival of sycamore nursery seedlings is satisfatory on both soil types and it ranges from 88,0 to 93,3 %. Flowering ash nursery seedlings have 100 % survival rate regardless of soil type, but survival of Flowering ash extracted from forest stands is different in relation to soil type. On agricultural soil this survival rate is satisfatory and amounts 93,3 %, while plants on forest soil have 56 % survival rate. Survival rate of willows and poplars ranges from 90,0 to 100 %. The best survival have plants which have been extracted from forest stands and been planted on forest soil, and plants from stands planted on agricultural soil have the lowest survival. Survival of nursery seedlings ranges from 92,0 to 90,0 %. Survival of Euro pean privet is in the range of 68,8 to 87,5 %. More successful are European privet plants planted on agricultural soil.
The results of this research indicate that adequate species of autochtonous and pioneer forest trees and species have been selected for revitalisation of this querry, taking into account their ecological requirements and biological features.
